To indicate different kinds of physical values , for models of 35R5GB/37R5PB
～
3500G, analog meters can be connected to the analog output terminals of AO1 and
AO2. Switch SW2 and SW3 on and off to select output voltage (0/2
～
10 V) or current
(0/4
～
20 mA).The wiring is shown as Figure 2-15:

Notes:
1
）
Dialing SW1, SW2, SW3 to “I” represents current, dialing to “V” represents voltage.
2
）
Analog input and output signals are easily disturbed by exterior environment, so
shielded cables must be used for wiring and the length of the cables should be as short
as possible.
3
）
When an analog output equipment be connected to the ac drive, sometimes because
of error act because of interference cased by the analog output equipment or the ac
drive, when which happened, a 0.01
～
0.1uF/50V capacitance or a ferrite bead(enwind
3 laps) could be connected to the analog output equipment.
